It is probably the condenser lines for the air-conditioner. The condensor
is another radiator-like unit mounted in front of the radiator.

You probably need to replace the heater valve. It is a small plastic valve
under the hood (connected to the coolant path in the back of the cylinder
head) that you control with the heater temperature control. If it doesn't
seal well in the "cold" position you'd have hot air. The heater valve is
an inexpensive part and is easy to replace.
